Nginx FastCGI cache

Example /etc/nginx/nginx.conf using FastCGI (e.g. to PHP-FPM) with FastCGI cache enabled. This will capture returned data and persist it to a disk based cache store for a configurable amount of time, great for robust full page caching.

Will need to create a directory to hold cache files, for the example given here that would be:

$ sudo mkdir -p /var/cache/nginxfastcgi
$ chown www-data: /var/cache/nginxfastcgi

React debouncing pattern for API calls

Classic debounce function:

const debounce = (fn, delay) => {
      let timer = null;
      return function (...args) {
          const context = this;
          timer && clearTimeout(timer);

timer = setTimeout(() => {
